Case Study on Cutting Cafeteria Costs. A cafeteria at All-State University has one special dish it serves like clockwork every Thursday at noon. This supposedly tasty dish is a casserole that contains sautéed onions, boiled sliced potatoes, green beans, and cream of mushroom soup. Unfortunately, students fail to see the special quality of this dish, and they loathingly refer to it as the Killer Casserole. The students reluctantly eat the casserole, however, because the cafeteria provides only a limited selection of dishes for Thursday's lunch (namely, the casserole).

• Define decision variables and describe the mathematical model; and

• Write a recommendation to the problem by including the total cost, the amount of each casserole's ingredient, and the amount of each nutrient.
